Leviticus 13:6-8

New Revised Standard Version Catholic Edition

⁶ The priest shall examine him again on the seventh day, and if the disease has abated and the disease has not spread in the skin, the priest shall pronounce him clean; it is only an eruption; and he shall wash his clothes, and be clean. ⁷ But if the eruption spreads in the skin after he has shown himself to the priest for his cleansing, he shall appear again before the priest. ⁸ The priest shall make an examination, and if the eruption has spread in the skin, the priest shall pronounce him unclean; it is a leprous^[a] disease.
